just click and it will test your clicks per second. I made this in a hurry so there might be some problems but I'm 99.9% sure there is not. I might add more/improve in the future but probably not._. my record is 13 cps.
It might not be 100% accurate because this is scratch and the way I tested it but it should at least very close to 100% accurate. - for the world record total clicks if you want to beat it just do a 100 second test (max length) because it doesn't matter how long your test was for that
